错误原因：貌似库cacti没有授权用户cacti@localhost
mysql> use mysql;
mysql> select user,host from user where user='cacti';
mysql> grant all on cacti.* to cacti@localhost identified by '123456' ; flush privileges;
mysql> select user,host from user where user='cacti';

按照上面的方法处理之后，还是报错，通过下面的命令，修改一下权限，ok了。
错误原因：cp的两个配置文件权限不对。
# chown -R nagios:nagios /usr/local/nagios/
